In 2005, the Left Alliance, which reunited the Labour Party, solidaritéS and the Indepenants, broke up because of difference. In the Genevan cantonal elections in the autumn of 2005, these parties failed to obtain the quorum of 7% of votes because of the divisions caused by the presence of a Communist Party List. The far left are excluded from parliament.

The following year, the far left were able to enter a communal project. The new coalition took the name of A Gauche toute! and joined the national coalition of the same name led by Vaudois Josef Zisyadis, who organised the far left at the national level.
